It would be nice to have Stalwart Soul acquired at the same levels the other tanks get their second AoE variation. Unlike the other tanks, DRK has to wait until 72 just to get their second AoE move; also, of all the things they could have done with BW, why they still have it on a timer is beyond me. Idk who's decision it was to keep it that way or if it's just the JPN community talking, but that is just awful.
Personally, I like the idea of removing the MP cost from TBN, putting it to 25 seconds, and perhaps adding some type of health benefit tying into the shield itself if it breaks (or not); perhaps, once it breaks or does not you get some kind of healing benefit, sorta like Heart of Conundrum. Then again, some people would probably not want that as it would be too similar. LD is another issue in itself as some people I talk to think it is a 20 second invul.
While I play DRK casually or just for fun even I see it as a WAR clone. I miss having Sole Survivor as at least if you didn't kill the enemy, you still got 20% HP and MP back vs. 30%, respectively. A new combo would have been sweet, but hey, that is asking for too much.
